No of course not,. My sandles are made by 'hotter' and I actually found them in TK Maxx. They are very similar to these
but they are lilac and I only paid about £17 for them
Clarks do quite a few shoes with removeable insoles (my mental health care co-ordinator has orthotics too so she gave me some handy tips!) mainly the 'unstructured' range she said. But I found these ones
, not to everyone's bag, and to be honest not what I would normally wear but falling with my daughter last year made me wise up to the severity of my problems.
So I now have black K Swiss trainers (didn't realise they had removeable insoles when i bought them a few yeras back, also from tk maxx) for day to day wear, the bronze clarks/kays mary janes I linked to above, and my hotter sandals for summer, ooh and how could I forget my trusty metallic purple DM's for the winter?!. I have to have my shoes altered to have lateral heel wedges too so I have to think about that when choosing shoes too, doesn't make it easy I tell you.
I'm sure some others can advise you some more too, Nemonie is pretty good with knowing brands of shoes etc that are good for orthotics
